I can see there is an oscillator on the board but wouldn't be surprised if we would still need the buffer board so it plays nicely. The SEC booster wouldn't need the MEGA ST buffer board. Is all the Ram, Rom and Flash run at the same speed as the CPU Exxos? Yes, for arguments sake, all at 50MHz.

This booster now the V2.3 booster which need external ROM board.. To re-cap... The ROM board was done in order to reduce costs for the booster board itself.. Basically the original V2.2 booster had the on-board ROM, was also a 6 layer PCB, which was very expensive.. So in order to reduce costs, the ...

Initially exxos wan't going to put the rom on but just a decode line out to the fast rom board. I haven't been watching that close so its nice he added the rom on. :excited: :excited: :excited: I think you are confusing this SEC booster with the V2.2. booster... The V2.2 booster needs a external RO...

Judging by this.. Its the drill holes that are the problem. SMD pads are fine. in the next revision i'll tighten the trace to trace and give more clearance to the drill point. Probably trace to trace 6.5mil and Trace to pad 8mil. The 0.8mm holes look ok on my board, looks like the smaller drill hol...
